Marketing. When operating as a consultant, you won’t necessarily be marketing your company; you’ll be marketing yourself. You’ll have to “package” yourself in a way that makes people trust you. For instance, if you’re marketing yourself as a financial consultant, ask yourself why someone would trust you with their life savings, and then figure out a way to convey that to potential clients. It might be in the form of a brochure, a portfolio, a sales letter, or all three.
Writing is a very lucrative online career that can do more than be a side hustle. It’s a good thing the internet is here to stay and here’s why. For like-minded individuals looking to transition smoothly from a cushy day job to a side hustle and turn the side hustle into the full-time job will need to dedicate themselves wholeheartedly to making the “writing side hustle” work for them. While a job is always good to have @ 1st because you need a roof over your head, one should focus more on entrepreneurship and not just having a job to pay the bills. That’s what the employer wants their employees to think and not be their own boss. Side hustles in my personal opinion bring out the best in everyone who makes good of writing online.
You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service, refunds and so on. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. Sound like a lot of work? Sure, it is. Especially if you do it all on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not.
